rllhis invention relates to machines for 'forming the heel seats and toes of shoes. An object of the invention is to provide a machine by use of which the work of forming the heel seats and toes of shoes is greatly expedited and the cost of manufacture largely reduced, and by use of which aA better and more refined article is obtained in respect of the formation of the heel seats and toes.

Another object is to provide a machine operative at a single operation to obtain the two results (one) of forming either the heel seats or the toes of Vshoes and (two) adhesively uniting the uppers and the soles artistically and in accurate conformation to the lasts in order to dispense with the use of staples and other fastening elements heretofore generally used to secure the uppers and soles together, preparatory for subsequent stitching operations.

Other objects will appear from the following description, reference being made to the drawings in whichT- Fig. 1 is a plan view of the machine.

lF-ig. 2 is a side elevation. g Fig. 3 is a cross sectional view'on 3-3 of lFig. 2.

Fig. 4 is a sectional View showing a art of the electric circuit structureby wich the heater is electrically heated.

Fig. 5 is a sectional View showing'- the relationship of the parts in operating to form the toe of a shoe. y

rlhe operative -mechanism of y the` machine'is supported by a frame l having a work supporting table 2 at its upper end upon which the shoes are -placed when being subjected tothe action of the machine An extension 3 from one side of the table may be provided to support the inner toe caps or other shoe parts to be embodied in shoes upon which this machine operates. Between the table 2 and the extension 3 a heatedsupport 4 is shown, an electric heater being conventionally shown therein the line in ldotted lines and heated by electric circuit wires 5 controlled by a switch 6. In the manufacture of'shoes for small children the inner toe caps A (Fig. 5) are sometimes of a composition material containing or carry. infr an adhesive substance which becomes softened and viscid under heat of about one hundred and fifty degrees, Fahrenheit, more or less, so that when the toe caps are placed tended portions of. the uppers smoothed and bonded Ito the soles ready for vthe heater with in position to be secured in the toesof the shoes the adhesive substance on the edges of the toe caps between the edges of the uppers and of the soles forms a connection securing the edges of theA uppers and the edges of the soles in proper relationship.

rllhe present machine is specially designed and adapted for use in the manufacture of shoes of that t e in which the toe and the heel portions ot the uppers are smoothed against the extremities of the lasts and seckllired to the soles. Heretofore it has been t e either wire staples or other similar devices which interfered seriously with the operation of the awls and stitching devices when the stitches were applied to fasten theuppers and soles together permanently. By the. present invention, which includes a heated presser for pressing the edges of the toe and heel portions of the uppers smoothly upon the soles with interposed adhesive material, the necessity of using staples or other fastening elements is eliminated, the exbeing the application of the stitches .to complete the shoes. close to the heated presser, is separated general practice to utilize fasteners, A

'llhe table 2, which is relatively' from bordering table portions 7 4which are 1' insulated from the heated table 2' by intervenmg spaces, as shown.

The presser comprises a heated metallic I plate l8 attached to" the' u per end of a rotative and vertically mova le shaft 9. The

plate 8 is heated by an electric heater 10 4to which electric current is supplied from Wires 11 and 12 controlled by the switch h. bracket l3supports a terminal contact member 14 for the wire 11 and a terminal contact member 15 for the wire 12, said contact members being mounted on a supporting and insulated therefrom and from each ot er. A wire 17 leading to the heater bolt 1 10 is in circuit with the wire l1 through a springmember 18 contacting with the contact member 14; and a wire 19 leading to is in circuit with av wire l2 through a spring member.- 20 contacting the contact member 15. Thus when the switch 6 is closed both the heated support 4 and the electrically heated. he heated support 4 conditions Afor use the adhesive material in or on the toe caps A, and the heated presser Tpresser plate 8 are plate 8 will press and smooth the extended heel and toe portions of the shoe uppers upon'the soles and adhesively secure them thereto.

The presser plate 8 is provided with a number of series of recesses in its side edge or edges. In the embodiment shown there are four series of recesses and four recesses in each series, of which the recesses 21 are the heel receiving recesses and the recesses 22 are the toe receiving recesses. Four recesses are needed in each series to operate upon the toes andheels of a pair of shoes. The pairs of recesses 21 and also the pairs of recesses 22 are of graduated sizes corresponding to the different sizes of shoes, so that as shown each side edge of the presser plate is constructed to complete the work upon the heels and toes of pairs of shoes of a certain size different from thesize of shoes worked upon by another side edge of the presser plate.

An arm23 1s attached to an insulation block 24 that supports the binding posts for the wires 17 and 19 andthe spring members 18 and 20, and which is rotative on the bolttx y16. A rod ,25, extending from the insulation member 26 on the -shaft 9, extends through a hole in the arm 23 so that the arm 23 and the block 24 will be turned with the plate 8. Thus, irrespective of the position ofthe presser plate, the circuit wires 11 and 1% are at all times in circuit with the heater A disc 27 supported upon a frame part 28 1s splined to the shaft 9, so that the shaft may move longitudinally through but cannot turn independently of said disc. The disc 27 has four peripheral notches 29 corresponding to the four side edges of the presser plate 8. A latch detent 30 is actuated by a spring 31 to engage the notches 29, respectively, and thereby hold the shaft 9 and the presser plate 8 from turning. Thus the presser plate may be latched in position to retain any selected side edge thereof toward the operator for continuous work upon shoes of a certain size, and may be turned to present any other side edge to the operator when shoes of a different size arek to be worked upon. A lever 32 is operative vto release the latch 30 from any notch 29 to permit the shaft 9 to be turned, as stated.

A link device 33 has swivel connection 34 with the lower end of the shaft 9 and also has connection with a treadle lever 35 where by the shaft 9 is moved downwardly to press the heated presser plate upon and to render smooth and to adhesively bond the heel and toe upper portions to the shoe soles. A spring 36 encircles the shaft 9 between the disc 27 and a collar 37 and operates to raise the shaft 9 and thereby the heated presser plate when the treadle lever 35 is released.

In operation the toe caps containing orv the toe cap and, by manipulation, shapes the" toe cap and the upper to conformity with the toe of the last, causing the edge of the toe cap to seat upon the edge of the sole and the edge of the upper to seat upon the edge of the toe cap, and the edges of said three shoe elements to become bonded to gether by the adhesive substance in the toe cap. This manipulation also causes that portion of the toe cap, the inner surface of which bears against the toe of the last, to become adhesively bonded to the inner side of the upper. After properly shaping the toe cap and the toeportion of the upper, as described, the operator places the toe of the shoe in one of the recesses 22 and operates the treadle lever 35, with the result that the heated presser plate 8 is pressed upon the edge of the toe portion of the upper, which is the uppermost one of the three superimposed shoe elements. This pressure by the heated presser plate smooths out the wrinkles and creases in the leather and securely bonds the three superimposed edges of the shoe elements together.

The heel seat of the shoe is formed by placing the heel of the shoe in one of the recesses 21 and then depressing the presser plate 8 upon the extended edge of the heel portion of the upper, with the result that the upper is adhesively united to the heel portion of the sole with sufficient strength to retain the connection until the shoe is completed by stitching the parts together in the usual manner.

It is apparent that the foregoing operations may be rapidly performed upon my machine, and experience has demonstrated that the output of a single workman is vastly increased over that which was possible by the old method consisting in the use of any device to shape the shoe upper in conformity with the last and then uniting the shoe elements by staples or other fastening devices, for the purpose of holding them together until the stitches were applied. ln factories having a relatively large output the saving is great; because the cost of manufacturing the shoes is greatly reduced, they are completed with greater speed, the output of each workman is greatly enlarged,-

and difficulties in sewing are avoided.

My invention obtains all of its intended objects and purposes in an eflicient manner. It is obvious that it may be varied widely without departure from the nature and principle of the invention.
